The family said he had bragged about killing, and they're afraid there may be at least one other victim out there.

The girlfriend, Joanna Bertram, confirmed she was one of two people to call police about a body buried in the backyard of the home she shared with Maxwell.

Bertram had specific information that led police to dig earlier in the week, but her brother, Alfred Bertram, said long before that she told them horror stories about Maxwell.

"They were very afraid of him," Alfred Bertram said.

Alfred Bertram said his sister was blind to the evils of Maxwell, and he said she wouldn't leave him.

But Alfred Bertram said his family managed to get Joanna Bertram's children out of the house in August -- and just in time, from what the children said.

"He would get drunk and hang out on the back porch, as they said, and would brag about how he killed two prostitutes," Alfred Bertram said.

Investigators found the body of an adult that had been buried more than one year earlier in Maxwell's yard.

Sources have said the victim is a woman, and the family of a prostitute, Chasity Starr, who has been missing from Holly Hill since January 2011, believes it's her.That fits with something else Alfred Bertram said Maxwell told the children.

"He told my niece and my sister that the last time he killed was in January. When he would brag about it, he would say the last time he killed was in January 2011, which was when Chasity Starr went missing exactly," Alfred Bertram said.

Bertram actually went to police twice last year about Maxwell's claims that he killed, but with no specific details, little could be done.

In December, Maxwell was arrested for kidnapping and raping a young neighbor. That troubles Alfred Bertram.

"If they had found evidence to maybe get Jim Maxwell off the street, maybe it couldn't have happened to that little girl," Alfred Bertram said.
